    Hello l.yeganeh,

    The option bytes are in fact located at the end of EEPROM memory area at adress 0x4800. It's here that the option bytes are programed by the tools (STVP or STVD). So to read option bytes you just have to read this address. If you want to write the option bytes (while application is running), please refer to the in-application programming (IAP) chapter of the STM8S Reference manual.

    Best regards,

    Seb
